Foxboro FBM218 P0922VW Communication Redundant Output Module
The Foxboro FBM218 P0922VW is an advanced redundant output interface module engineered for high-availability process automation systems. Featuring eight isolated output channels, this module supports both HART protocol communication and standard 4-20 mA analog signaling, making it ideal for critical control loops in oil & gas, chemical processing, power generation, and pharmaceutical manufacturing environments.
Technical Specifications
- Output Channels: 8 isolated analog outputs
- Signal Type: 4-20 mA with HART digital overlay
- Redundancy: Full redundant operation with automatic failover
- Isolation: Channel-to-channel and channel-to-bus isolation
- Resolution: 12-bit D/A conversion
- Update Rate: Configurable, typically 100 ms per channel
- Power Consumption: 5W typical from Fieldbus Module Base
- Operating Temperature: 0°C to 60°C (32°F to 140°F)
- Compliance: CE, UL, CSA, ATEX, IECEx certified
Key Features & Benefits
Redundant Architecture: Dual-channel redundancy ensures continuous operation even during module failure or maintenance, eliminating single points of failure in critical control strategies.
HART Communication: Simultaneous analog and digital communication enables advanced diagnostics, remote configuration, and asset management without interrupting the 4-20 mA control signal.
Galvanic Isolation: Each output channel is electrically isolated to prevent ground loops, reduce noise coupling, and enhance system reliability in electrically harsh industrial environments.
Application Solutions
Distributed Control Systems: Integrates seamlessly with Foxboro I/A Series DCS platforms for coordinated control of complex process units including distillation columns, reactors, and heat exchangers.
Safety Instrumented Systems: Supports SIL-rated safety loops when configured with redundant controllers and field devices, meeting IEC 61508 and IEC 61511 functional safety standards.
Valve & Actuator Control: Drives smart positioners and control valves with precise 4-20 mA signals while leveraging HART for valve diagnostics, travel monitoring, and predictive maintenance alerts.
Analyzer Integration: Interfaces with process analyzers (pH, conductivity, dissolved oxygen) to maintain optimal process conditions through closed-loop feedback control with real-time calibration data via HART.
Installation & Configuration
The FBM218 mounts directly onto a Foxboro Fieldbus Module Base (FBM2XX series) with hot-swappable capability for maintenance without system shutdown. Configuration is performed through Foxboro Control Core Services software, supporting both simplex and redundant topologies. Termination assemblies (sold separately) provide field wiring connections with compression or screw-terminal options.
